Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual creation of transport schedule is used, then flexibility to handle production schedule changes is maintained, but time consumption and labor burden increase significantly
Solution Approach 1:
The transport schedule creation system performs self-service by automatically generating optimized schedules without human intervention. The schedule creation unit autonomously calculates transport paths, determines transport timing, and creates schedules based on production schedule information, eliminating the need for manual schedule recreation while maintaining adaptability to changes.
Solution Approach 2:
The patent replaces the manual mechanical process of schedule creation with an automated information processing system. The schedule creation unit uses computational algorithms to substitute human operators, processing production schedule data and generating transport schedules automatically, thereby reducing time consumption while preserving flexibility.
2Adaptability or versatility
If manual creation of transport schedule is used, then complex production schedule changes can be handled, but labor burden on personnel increases
Solution Approach 1:
The system performs self-service by automatically handling complex production schedule changes without requiring human operators to manually adjust schedules. The schedule creation unit processes various production scenarios autonomously, calculating optimal transport schedules that adapt to complex changes while eliminating labor burden.
Solution Approach 2:
The patent replaces manual operational processes with an automated information processing system. The schedule creation unit uses computational methods to substitute human operators in handling complex schedule changes, thereby maintaining adaptability while significantly reducing labor burden and improving ease of operation.
3Productivity
If automatic schedule creation is implemented, then time consumption and labor burden are reduced, but complexity of the scheduling system increases
Solution Approach 1:
The scheduling system is segmented into distinct functional units: a schedule creation unit that generates schedules, a transport path determination unit that calculates routes, and a schedule management unit that handles schedule data. This segmentation manages system complexity by dividing the automatic schedule creation process into modular, manageable components while maintaining high productivity.
Solution Approach 2:
The patent introduces an intermediary schedule creation unit that acts as a mediator between production schedule information and transport device control. This intermediary processes production schedule data, calculates optimal transport schedules, and outputs control instructions, thereby implementing automatic schedule creation while managing system complexity through a structured intermediate processing layer.
4Adaptability or versatility
If transport device moves to all work positions, then product transport flexibility is improved, but unnecessary movements increase
Solution Approach 1:
The schedule creation unit dynamically changes transport schedule parameters based on real-time production needs and product locations. By adjusting transport timing, routing, and frequency according to actual requirements, the system maintains product transport flexibility while eliminating unnecessary transport device movements and reducing energy consumption.
Solution Approach 2:
The system applies partial action by transporting products only to work positions that require them, rather than moving the transport device to all work positions regardless of need. The schedule creation unit calculates precise transport requirements and executes only necessary transport operations, thereby maintaining flexibility while avoiding excessive movements and energy waste.
